Re: Recently acquired 1490

Only the correct turbo produce the correct pressure at the correct engine revolutions in the inlet manifold. The pressure needed is based on the wanted horsepowers and maximum polution allowed and is a result of many calculations and tests made by the engine manufacturer and the turbo supplier. Amon...

Re: Recently acquired 1490

In the link to the partrs catalogue page for the turbo I supplied, a information says that the turbo is made by Schwitzer and no alternatives are listed. The 1410 and 1412 had a Holset turbo.

Re: Recently acquired 1490

I fear that there is a lot more that has been completely messed up with on this tractor.

Re: Thermostart Interchange

Well, you can have the throttle wide open when you crank the engine, but you must reduce the engine revs as soon as the engine starts. Having the engine idling will make it possible to keep the thermostat working during the engine low idle. The flame will die if you increase the engine revs above lo...

Re: 1490 4wd

Tyres are not tractor related. Ask on e-bay or contact your local tyre shop.

Re: 1490 gearbox lubrication pipes

Its a long time since I have been stripping down a gear box. The small pipe looks to be in the middle of the gear box, sugesting that the oil from the pipe is directed to the rear of the top shaft in the gear box.

Re: 1490 gearbox lubrication pipes

I can not find out what pipe you mean by reading your explanation as you do not even say if the pipe you are talking about is on the left or right hand side. The following is a link to the parts catalogue shoving the pipes inside the rear axle. https://partstore.caseih.com/us/parts-search.html#epc::...

Re: Recently acquired 1490

The road speed should be around 15,7 MPH for a synchro box and 16 MPH for a Hydrashift box. Both at engine speed 2200 RPM and with 18.4-30 tyres.

Re: Recently acquired 1490

Sorry about that. The 1490 was available only as turbocharged. The picture you supplied looks a little bit odd and half of the turbo is not shown. Regarding the fueling. the maximum fueling is just a little bit more for a turbocharged David Brown engine if you compare it to a non turbo. The question...

Re: Recently acquired 1690

There was two versions of the 1690, turbo and non turbo. Please check the serial number to see if the model designation has a "T" (turbo) or not. Please have a look in the following link, showing the David Brown tractopr range https://dbtc.co.uk/index.php/information/tractor-range Many attempts have...

Re: Thermostart Interchange

The time for the flame to burn is determined by the operator and the piping has nothing to do with this. The flame will burn for as long as the driver keeps the igniotion key in pre-heat position. The piping size and the size of the reservoir together must be big enough to be able to hold fuel for a...

Re: Thermostart Interchange

I have been working with David Brown tractors fo 45 years and I have never heard or seen any different Thermostarts. To me they are all the same. Many of the comments on different forums are made by people with little or no real understanding about topics they are commenting on. Remember that you ha...
